Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1923-01-26
Abstract: 205,002. British Thomson - Houston Co., Ltd., (General Electric Co.). Jan. 26, 1923. Cut-out systems.-In an automatically-reclosing circuit-breaker system particularly for a direct current supply circuit an auxiliary source of alternating current is connected to the load circuit when the circuit-breaker opens and the re-closing is effected by a wattmeter relay responsive to the watts supplied to the load from the auxiliary sources. In the arrangement shown in Fig. 1, the main circuit-breaker 3 is maintained closed by the coil 7 energized from the source 1 through the contacts 14, 15 of the slow return overload relay 12 and the back contacts 8, 10 of the circuitbreaker. On overload the contacts 14, 15 separate the circuit-breaker opens and the back contacts 9, 11 are closed. This connects a low voltage alternating current source 16, 17 through the limiting resistance 23 and through the current winding 21 of a wattmeter relay to the load 2 through a condenser 27 which prevents the passage of direct current, The voltage coil 22 of the relay is connected across the load. When the resistance of the load increases sufficiently, the watts supplied thereto are adequate to close the relay contacts 24, thereby completing a re-closing circuit from the source to the winding 7. In a modified construction, additional back contacts on the circuitbreaker become closed when the circuit-breaker opens and complete a circuit from the source 1 to a motor generator which supplies the auxiliary testing alternating current to the load. In this arrangement the resistor 23 is replaced by a condenser.

Title: Improvements in or relating to die casting machines for moulding material when in a plastic condition
IPC: B29C45/07
Filed: 1944-02-15
Abstract: 580,097. Injection-moulding machines. PLASTICAST DEVELOPMENTS, Ltd., and STOCK, H. A. Feb. 15, 1944, No. 2750. [Class 87 (ii)] [Also in Group XXII] A plurality of injection cylinders are mounted for rotation in turret fashion about a fixed axis, each cylinder being adapted by such rotation to be brought individually into mould filling position with its discharge nozzle in register with the mould filling aperture, the mould being so moved by hydraulic means that its filling aperture engages the nozzle registering therewith. The mould may have a plurality of filling apertures engageable by a plurality of nozzles. The cylinders may be horizontally disposed, rotating about a horizontal axis (Fig. 10, not shown), or may be vertically disposed, as shown. Three injection cylinders 59 are mounted on a rotatable turret 13 supported by a carriage 23 slidable on the bed A of the machine. Each cylinder has a horizontally-extending nozzle 11, and is in two parts 24, 24a, which are relatively rotatable so that a plurality of nozzles may be aligned with a plurality of mould filling openings. The turret 13 is rotated uni-directionally by a hydraulic cylinder 19 via rack bar 37 and pinion 38 which are coupled to the turret spindle 60 by a pawl and ratchet drive. The turret is locked in postition by a pin 21 operated by a hydraulic cylinder 22. The hopper 25, hydraulically-operated injection plungers 29 and material-delivery device M are all mounted on the carriage 23. The mould halves 1, 2 are slidable mounted on four horizontal bars 17. Operation:-The movable half 1 is pushed to the right by hydraulic cylinder 3, to engage mould half 2. Both halves then move on together, compressing springs (not shown) disposed around bars 17, and seating the aligned nozzles 11 in the mould half 2. Then the whole carriage 23 is pushed to the right against springs 15. The mould halves are locked in closed position by vertically-movable wedges 9a which are inserted by hydraulic cylinders 7a between fixed abutments and the rear of the mould-carrying platen 4. The aligned plunger 29 then descends to force heated material from the cylinder into the mould, and as it does so a bar 30 depresses a slide 26 and transfers a measured quantity of material from hopper tube 56 to cylinder delivery shoot 35, where it rests until plunger 29 rises. The mould halves then retract to the left and separate, the moulded article being ejected from mould half 1 by pins (not shown). The turret plate 13 is then indexed to bring another cylinder into mould-charging position.

Title: Weight determining device
IPC: G01G3/16
Filed: 1949-02-03
Abstract: 658,807. Current and voltage measuring. AMERICAN MACHINE & FOUNDRY CO. Feb. 3, 1949, No. 3020. Convention date, March 3, 1948. [Class 37] [Also in Groups XVIII, XXXVIII and XL (b)] A machine for weighing small articles, e.g. cigarettes, at high speed by comparing the time for one vibration cycle of a vibratory structure supporting one article with that of a standard vibratory structure employs an electronic circuit in which condensers associated with each vibrating structure are charged during a fixed part of the vibration cycle, and the charging voltages are compared on a meter. In one embodiment, Figs. 1 and 2, the sampling structure 10 is suspended for vibration between four coils L-1A, L-1B, L-2A, L-3A, and may be held by the attraction of an electromagnet 50, the standard structure 30 being similarly supported between four coils L-4A, L-4B, L-5A, L-6A over an electromagnet 52. The electrical circuit associated with each structure is similar. As shown for the sampling structure 10 coils L-1A, L-1B are energized from a 400 kcs. oscillator 0 (Fig. 3), and are inductively coupled to coils L-2A, L-3A through an electrostatic screen 17 attached to the structure 10, and so situated that in the mean position, of structure 10 the voltages induced in coils L-2A, L-3A are equal, but with vibration of structure 10 these voltages become unequal. Thus the output from a full-wave rectifier VT-2 associated with these coils is an A.C. whose frequency is determined by the vibration frequency of structure 10, and after filtering, is as shown in Fig. 4. This voltage is fed to the grid of valve VT-3 whose anode circuit contains a resistance TR1 and condenser TC1, so that the anode voltage is a saw-tooth wave (Fig. 6). This voltage is fed to the grid of valve VT-4, which has a high cathode bias determined by potentiometer RD1, RD2, so that a predetermined amount B of the rising grid voltage does not affect the anode current, and the remainder CD, produces a square pulse anode voltage (Fig. 8), which when fed to the grid of valve VT-5 gives a saw-tooth wave (Fig. 11). This voltage on the grid of valve VT-6 produces a build-up of voltage on a condenser SC in the cathode lead, which voltage is measured through a valve VT-7 on a meter A. The vibration of structure 10 is restricted to one cycle by the periodic energization of electromagnet 50 from a valve VT-9 which has a cam-operated switch S in its cathode lead, the same cam mechanism causing a valve VT-8 to discharge condenser SC. An exactly similar circuit is associated with the standard structure 30, so that meter A notes the difference in vibrating period for each article, a mechanical arm 74 (Fig. 1), changing the article on structure 10 after each cycle. In another embodiment (Fig. 13) the screen 17 is replaced by a shutter 100 periodically allowing light from a source 104 to fall on a photo-cell 102 to give the required input to valve VT-3.

[Classes 83 (ii) and 83 (iv)] [Also in Groups XXVIII and XL (a)] Stamping.-A combined arrangement of metal sheathed getter wire and a heating element for use in thermionic valves or other evacuated envelopes is produced by tightly enfolding the wire 68 in a turned-over portion of a thin metal stamping 67 or of a metal strip from which lengths may be stamped, the remaining portion of the width of metal being adapted for eddy current heating. The metal strip may be doubled over or have one edge turned over, and the strip, which is preferably nickel enfolding nickel-sheathed barium wire, is seam welded as close to the sheathing as possible to ensure good thermal contact with the wire. In the operation of stamping getter tabs from composite strip, the ends 70, of the getter portion are tapered and closed, Fig. 2b, to shield the getter from the atmosphere and to reduce the wall strength opposing flashing of the getter. In the stamping illustrated the getter portion is cut-off shorter than the length of the stamping and a hole which may be adapted in shape to suit the electrode supporting structure is provided in the heater portion.

Title: Improvements in or relating to the manufacture of polymerised organic compounds
IPC: C08F18/04
Filed: 1931-02-02
Abstract: Ester condensation products.--The polymerization of vinyl esters and their homologues and esters of acrylic acid and their homologues and derivatives, is effected with these substances in emulsion with soap-like emulsifying agents.  The derivatives of acrylic acid esters are defined as having a double bond in the a -b  position to the esterified carboxylic group.  Suitable catalysts may be added, and this process may be controlled when the reaction is exothermic, by adding further cold dispersion medium or by reduction of the pressure.  Preferably closed vessels are employed.  The polymerization may be assisted by ultra-violet light.  The dispersion medium may be water or aqueous solutions, and chlorinated hydrocarbons may be added.  As emulsifying agents may be used naphthene sulphonic acids, or their soaps, sulphonated castor oil or its soaps or other known soap-like emulsifying agents.  Organic or inorganic peroxides, gaseous or vaporous substances such as air, oxygen, nitrogen oxides, and organic acid anhydrides, acetals, aldehydes, and the like may be used as catalysts.  In the examples (1) acrylic acid methyl ester emulsified with aqueous sulphonated castor oil or its soaps is polymerized with a peroxide in a closed vessel, the heat being absorbed by addition of cold water or by evaporation; (2) a mixture of acrylic acid methyl ester and vinyl acetate is emulsified as in the first example and polymerized by air or oxygen; (3) a similar emulsion of vinyl acetate is polymerized with a peroxide.  The Specification as open to inspection under Sect. 91 (3) (a) includes the polymerization of other organic compounds, especially unsaturated compounds with any suitable dispersion media and emulsifying agents.  The dispersion media mentioned are saturated hydrocarbons, chlorinated hydrocarbons, benzol, "saturated heavy benzol," petroleum fractions "or alcohol and hydrocarbons or chlorinated hydrocarbons which dissolve the esters may be employed as dispersion accelerators."  Emulsifying agents mentioned are known substances for decomposing fats, glycol ethers, amino compounds of the polyglycols, and aliphatic amines.  Glacial acetic acid is mentioned as a catalyst.  This subject-matter does not appear in the Specification as accepted.
